If you compare the input signal to the output then yes the threshold is moving relative to the amplitude of the wave, but moving the threshold cannot replicate what we are trying to achieve with this trick. So I dont think you should visualize it this way.
That´s what I (thought) I said
"Idea is basically/kinda the same, but it´s not THE same".
The concept is in the same ballpark, although the end result isn´t the same.
But I guess you´re right, maybe that just created further confusion.
eg Using a 24bit vox signal unprocessed on the way in and now mixing.
1. set the comp up for the verse so it levels out nicely eg 3db max peak reduction.
2. when the chorus comes the singer will often sing so much louder that the compressor is crushing/distorting the signal to death. eg 13db max peak reduction.
So if for the chorus you can ride the fader down (10db) that feeds the compressor you have only 3db compressor peak reduction again. (in reality it will be a bit more )
So you have achieved 10db of transparent "manual compression" and reinstated 3db compression.....end result is the chorus vox sounds as undistorted and clean as the verse.
Exactly. And most of the time I also bring up some passages and little nuances, which is actually expanding, not compressing.
(For anyone interested, here´s a video about the concept :

In reality I dont ride the fader with my finger (some do). I put the comp post fader and draw the fader moves into my daw automation.
Me too
